The campaign consists of three scientific payloads (LEE, AESOP and Hi-Wind) during May - July 2011 with balloon flights westwards and landing in Alaska or Canada.
NASA summer campaigns
The first NASA summer campaigns (2005) demonstrated a new long duration, heavy payload balloon capability from the northern hemisphere to the international science community. SSC and NASA combined their resources and experiences to offer significant new opportunities for US and European scientists to fly sophisticated instruments in near space for periods of up to 10 days at very low cost.
Until today the following flights have been performed
AESOP was launched on 2 June 2006 (test flight)
ULDB was launched 11 June 2006
TRACER was launched on 8 July 2006
BLAST was launched on 12 June 2005
LEE, was launched on 17 May 2009
AESOP, was launched on 5 June 2009
SUNRISE, was launched on 8 June 2009
ULDB was launched on 21 June 2009
The 2011 balloon campaign is a continuation of a NASA long-duration balloon flight programme at northern latitudes. By conducting balloon flights from the Esrange Space Center in northern Sweden to North America, flight of up to 4-6 days can be obtained, an opportunity that is highly required by scientists within the field of astronomy.
LEE was launched on 27 May 2011 at 01.21.38 UT
AESOP was sucessfully launched on June 10 2011 at 00:19 UTC
Hi-Wind was successfully launched on June 13 at 23:11 UTC
The main purpose of this campaign is to measure heavy cosmic ray and the magnetic fields importance in propagation of the cosmic ray.
Two payloads, Anti Electron Sub-Orbital Payload (AESOP) and LEE will measure propagation of charged cosmic ray particles from Local Interstellar Space to Earth and the magnetic fields importance in propagation of the cosmic ray.
These two payloads have been flown earlier from Esrange Space Center, USA and Antarctica. Hi-Wind is a balloon borne Fabry-Perot interferometer that will measure the thermospheric winds by monitoring the neutral wind induced Doppler shift in the airglow emission O 630 nm.
Colombia Scientific Balloon Facility (CSBF) has the overall operational responsibility for the campaign activities and they will be supported by a particular project manager and a launch team from the SSC.
